LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 290,728, dated December25, 1883.

Application filed June 25, less.' (Model.)

To all whom it may concern,.-

Be it known that we, DANIEL APPEL and ROBERT G. MCAULEY, of Cleveland,in the county of Cuyahoga and State of Ohio, have invented a certain newand Improved Lubricator; and we do hereby declare that the following isa full, clear, and complete description thereof.

The special purpose of the above-said lubricator is for lubricating thecylinder and valves of locomotive-engines automatically by injecting theoil to the valves by steam-pressure, substantially as hereinafterdescribed, and illustrated by the accompanying drawings, making a partof this specification, in which- Figure l represents a side view of thelubricator, partly in section; Fig. 2 is a vertical section takenthrough the line x xof Fig. 3. Fig. 3 is a top view. Figs. 4, 5, 6, 7,and 8 are detached sections, to which reference will be made.

Like letters of reference refer to like parts in the several views.

As shown in the drawings, A represents an oil-vessel, which, by means ofthe neck B, is screwedinto the steam-boiler or any such place as may bemost convenient for-the engineer to obtain access thereto.

' C indicates a portion of said boiler, and D a pipe extending from theneck down into the water and in open communication therewith. Saidwater-pipe is also in communication with the oil-vessel A by means ofthe conduit E in the neck B and the pipe F, one end of which is screwedinto the conduit. The pipe extends therefrom up into the oil-vessel,near to the top, and returns down to the conduit G, and terminates ashort distance above it, and in alignment therewith, as seen in Fig. 2.

In the side of the neck B, above alluded to, is inserted a screw-valve,H, of which a is the seat for opening and closing the communicationbetween the boiler and the oil-vessel.

I is a glass tube, the lower end of which is secured in a'tubular arm,J, by a screw-cap stuffing-box joint, which is or may be like suchjoints in ordinary use; hence a description thereof is not essential inthis place. The

upper end of the tube is, in like manner, se-

cured to a tubular arm, K, having a stop-valve at V, by which the upperend of the glass tube is put in open relation with the oil-vessel,

Awhereas the lower end of the glass tube is put in communication withthe bottom of the oilvessel by the tubular arm J and conduit G, withwhich the bore of the tubular arm is in open communication, as shown inFig. 2. The end of the tubular arm J terminates in an enlargement,forming a valve-chamber, L, in which is inserted a screw-valve, M, ofwhich b is the seat. Said valve and its housings are a duplicate of thevalve H, above referred to, and are for the purpose of opening andclosing the communication between the oil-vessel and the glass tube, ashereinafter set forth.

The valve-chamber L, above alluded to, is provided with an outlet, N,opened and closed by a stop-cock, O, Figs. 1 and 2.

v On the upper end of the oil-vessel is screwed a cap, P, of which thetubular arm K forms a part, as seen in Fig. 2. By means of a tubularprojection, Q, is secured in the cap of the oil-vessel a cylinder, E, inwhich is tted an elongated piston, S, provided at each end with aguide-rod, respectively, T and U, made closeitting in the heads Aand Bof the cylinder by stuffing-boxes, substantially the same as thestuffing-boxes above alluded to.

In one side of the piston is a longitudinal groove, a, Fig. 2, extendingfrom one end thereof to about three-fourths of its length. Quartering inrespect to the groove a is a similar groove in the side of the piston,as indicated by the dotted lines b. Said groove b commences at theopposite end of the piston from that of the groove a, and is about thesame length.

It will be observed in Fig. 2 that the groove a is in open relation withthe tubular way C', and that the groove b is turned away therefrom andcovered wholly by the side of the cylinder.

It will be noticed in Fig. l that in two 0pposite sides of the cylinderE there is an oileduction port or conduit, c and d. Said conduits extendto and terminate, respectively, in the tubular arms D and E'. To theends of each of said tubular arms are connected by any suitablepipe-coupling the tubes F and G', by means of which the lubricator isput, respectively, in communication with the steamchests of thecylinders of the engine for lubricating the valves thereof.

e and f are a pair of balance-valves placed, respectively, at the junction ofthe oil-eduction ports or conduits c and d and the tubulararms D and E. The use of said valves will presently be shown.

The piston S, above described, is given a rotative movement in thecylinder by means of the following mechanism: On the end of thepiston-rod U is secured a head or block, II', Fig. 2, enlarged detachedviews of which are shown in Figs. 4, 5, 6, 7, and 8, representingdifferent sides and ends of the head. On each of two opposite sides of'the said head is an inclined plane, g g, respectively extendingdiagonally from the corner c to the corner b.

In Figs. 2 and 4 one of the inclined planes, 0, only is seen. In Fig. 5both are shown. Said Fig. 5 represents an end view of the head, and Uthe piston-rod. On the two other sides of the head is also an inclinedplane, c and d', similar to the inclined planes g g', but in a reversediagonal direction, as shown in Fig. 8, both of which are shown in Fi 7which represents an end view of the head. The said in clined planes arealso shown in Fig. 4.

It will be noticed in the drawings that the two corresponding inclinedplanes g and g are of equal length and terminate at the projection orlip fi, Figs. 4and .3. So also are the inclined planes d and c of equallength and terminate at the projection or lip a, Figs. 4 and 8.

To the top of the cylinder R is secured a bifurcated spring, I', Fig. 2,a section of which only is shown in Fig. 3. Each branch m and m of saidspring is provided with a pin, respectively, 7L and h, which are adaptedto rest upon the inclined planes, as seen in Fig. 6, in which m and mrepresent the two bifurcated branches of the spring, and 7L h the pinsalluded to.

The use of the bifurcated spring will hereinafter be shown.

rIhe practical operation of the above-described lubricator is asfollows: As aforesaid, the lubricator is screwed into the steam-boiler,so that the pipe D may extend down into the water. The pipes Fl and Gare respectively connected to the steam-chests of the cylinders of theengines. (Not shown in the drawings.) The oil-vessel`is charged with oilat K, Fig. I. New, in order to force the oil from the vessel A into asteam-chest, the valve H is opened, as shown in Fig. 2, thereby allowingwater from the boiler to pass upward into the conduit E to the pipe F,through which it as cends and returns through the branch F" to thebottom of the oil-vessel. The pressure of the water on the bottom of theoil forces it upward through the conduit C into the groove a of thepiston and passes therefrom into the space X', between the end of thepiston and head of the cylinder, which forces the piston in thedirection ofthe arrow. "When the piston has arrived at the end of itsstroke (which is the length of the inclined planes g and 'g'. up whichthe pins in the ends of the spring I slide, by virtue ofthe longitudinalmovement of the piston) it receives a quarter-turn by means of the pin7i of the branch m of the spring, having passed from off its inclinedplane g, while the pin h of the branch m of the spring passes onto theprojection or lip a.

The continued pressure of the spring m on the lip a (and there being nopressure of the spring m on the inclined plane g) causes a quarter-turnof the head,W or to the position shown in Fig. 8. In said position thetwo pins of the branches m and m of the spring will be down upon the lipa. The pressure of the two springs being now exerted equally .onbothsides of the axial line of the head prevents it from further turning. Atthe same time the two springs are in position to slide up the inclinedplanes c and d. The abovcssaid action brings the groove a of the pistonto the outlet-port e. rlhis opens a free communication from the cylinderto the balance-valve c, which will be at once opened by the superiorpressure of the oil on the upper end of the valve, due to the differenceofthe area of the end of the piston, as compared with that of the valve.The valve being opened, the oil is at once forced into the steam-chestof one of the cylinders, conducted thereto by the pipe F.

The rotative action of the piston, above described, in changing thegroove a from the passage C to the outlet-port c, has brought the grooveb to the passage G and closed it against the groove a. The oil nowpasses from 4C into the groove b, thence to the opposite end of thepiston,which causes a reverse longitudinal movement thereof from thatabove described. As the piston moves back in the opposite direction ofthe arrow the pins of the springs ascend their respective inclinedplanes. On their arrival at the upper end thereof the spring m passesfrom off its inclined plane, while the spring m passes onto theprojection or lip z', (now at the upper side of the head.) The pressureof the spring m on the one side ofthe head, and none on the other sideby the spring m, rotates the head to the position shown in Fig. 4-aquarter-turn-thereby bringing the groove b in open relation to theoutlet-port d, and the groove a again to the passage C, as shown inFig. 1. This changed position of the piston opens a free communicationfrom the cylinder to the balance-valve f, which is at once opened by thesuperior pressure of the oil,.-as was the valve c, above described. Thevalvef being opened, the oil is at once forced into the steam-chest ofthe second cylinder, conducted thereto by the pipe G', and cut off frompassing into the iirst one above instanced by the closing of the.outlet-port c by the rotative action of the piston'.

For again -oiling the Erst-mentioned steam- IOO IIO

cylinder the operation is repeated, as in the first instance, and so onalternately each steam-cylinder is supplied with oil at each alternatereverse action of the piston, caused by the operation of the head ofinclined planes and the bifurcated spring in its co-operation therewith,the two operations being substantially alike, differing only in beingreversedthat is to say, the one acting to the right and the other to theleft. The two operations of the inclined planes and the springs foroperating the piston are substantially alike, but act reversely.

It Will be proper to remark here that the normal pressure of the waterin the boiler tends to keep the balance-valves closed; hence the pistonwill have a certain amount of rc- `sistance to overcome at all times, sothat a withdrawal ofthe pressure from the discharging-pipes F and G', inconsequence of shutting oft` the steam from the engines when go-4 ingdowngrade, will not interfere withvthe working of the lubricator.

When the oil is exhausted from the vessel A, which will be shown throughthe glass tube I, the pressure-valve H is then to be closed and the cockO and valve M opened to allorir the water in the oil-vessel to be drawnoff, to be again filled with oil through the opening at IC, abovealluded to.

The valve V is to prevent the oil from iowing from the vessel in theevent the tube I should get broken.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. In a lubricator for oiling locomotive-engines, the cylinder R andpiston, provided with grooves a and b, arranged quartering in relationto each other, and alternately in open communication with theoutlet-ports c and d, conduit C', and oil-vessel, substantially asherein described, and for the purpose specified.
